The Nevzorov liquid water content (LWC) and total water content (TWC) probe is a constant-temperature, hot-wire probe designed for aircraft measurements of the ice and liquid water content of clouds. The probe consists of two separate sensors for measurements of cloud liquid and total (ice plus liquid) water content. Each sensor consists of a collector and a reference winding. The reference sensors are shielded from impact with cloud particles, specifically to provide an automatic compensation for convective heat losses.

The 2D-C/P Hydrometeor Imaging Probe (2D-C/P) is an in situ, airborne instrument that captures imagery of hydrometeors. It collects these images by recording the status (illuminated or shadowed) of the photodiode array as the shadow of the hydrometeors passes over. 2D-C/P also provides measurements of particle size distribution, cloud droplet concentration, and hydrometeor shape. Typically, 2D-C/P probes have an image resolution of 25 micrometers and can image hydrometeors with diameters up to 1600 micrometers.

The King Probe is an airborne cloud probe developed by Warren King (Commonwealth Scientific and Industrial Research Organisation) and manufactured by Particle Measuring Systems (PMS) and Droplet Measurement Technologies (DMT). The King Probe provides measurements of cloud liquid water content (LWC) by measuring the heat released when water droplets are vaporized. The King Probe operates at a constant temperature (~100 C) and has a data output rate of 1 to 10 Hz. It is typically used in cloud microphysics and aircraft icing studies.

The NRC Airborne W and X-band (NAWX) radar system has polarimetric and Doppler capabilities at both wavelengths and can switch electronically between zenith, nadir and side looking antennas. The NAWX radar system has the following capabilities: pulse compression and frequency hopping capability at W-band for improved sensitivity and range and temporal resolution; space qualified W-band tube with1.9 kW peak power and 3% duty cycle, designed for the CLOUDSAT mission; electronic switching at both frequencies, allowing near-simultaneous sampling of the atmosphere in three planes along the flightline using six antennas; innovative design incorporating NRC-developed INS-GPS integrated navigation system for real-time Doppler correction; and synchronized operation and data collection for dual-wavelength analysis.

The Forward Scattering Spectrometer Probe (FSSP) is an in situ airborne optical particle counter originally designed by Particle Measuring Systems, Inc. It provides particle size distribution by measuring the intensity of the light scattered by individual particles within the cloud. FSSP can detect particles within a diameter range of 0.5 to 47 μm. It operates at a wavelength of 633 nm and has a typical sampling frequency of 1 Hz.
